Meteorite

A team of scientists believes they have discovered the first extraterrestrial protein known to humanity. Using a new analysis technique, the researchers claim to have found the out-of-this-world discovery inside a meteorite that fell to Earth some 30 years ago.

The discovery is just the latest to show that meteorites are much more than space debris that falls out of the sky. Recent investigations have turned up meteorite-borne deliveries of possible extraterrestrial proteins, minerals and materials older than the Solar System itself. But we have never seen anything quite like this before.
